What is the ruling on saying: "I didn't believe in Allah," "You did your part for me, and the rest is up to Allah," "May Allah shake you," "May Allah wrong you," "May Allah disgust you," "May Allah uproot you," "May Allah burn you," "May Allah humiliate you," and "May Allah hate you"?

First, consult the scholars in your country regarding the meanings of these phrases in your local dialect. It is permissible to say, "I did such-and-such, and the rest is up to Allah." As for "I didn't believe in Allah" (ما صدقت على الله), if it means "I wasn't truthful with Allah" (ما صدقت مع الله), then there is no harm in it for someone who lied about their Lord. The statement "May Allah wrong you" (الله يظلمك) is not permissible, because Allah Almighty says: {And your Lord wrongs no one} (Quran 18:49), and in the Hadith Qudsi: "O My servants, I have forbidden injustice for Myself." It is also forbidden to supplicate against people unjustly with words such as "May Allah disgust you," "May Allah uproot you," "May Allah burn you," "May Allah disgrace you," "May Allah make you hateful."
